SARA has pioneered the development of low cost, high accuracy radio frequency direction
finding systems for airborne and ground systems, including homing seekers and geolocation
systems.

Functionality

SARA has made a breakthrough in the area of compact, very low cost (1/10th the production cost of prior-generation systems), solid state (no moving parts) sensors and seekers designed to detect, point toward and enable guidance and/or geolocation to sources that radiate radio frequency (RF) energy. Our seekers use a common munition interface which provides a rapid, low cost integration solution. SARA’s “Home on Jam” (HOJ) family of seekers have been demonstrated in multiple captive and live-fire /free-flight tests. Should an enemy strive to complicate the battlefield by stray or competitive RF energy, SARA’s HOJ subsystems can enable a host guided bomb or missile to engage it as the system or operator might prefer.
SARA’s seekers have been demonstrated on front-line US weapons launched from front-line US aircraft, and extensively modeled against a wide-variety of enemy lay-downs and engagement approaches.

When hosted on a bomb or missile; SARA’s subsystem can detect, acquire and enable
guidance by the guided bombs or missile. When the host is a collaborative system
(that is, when it is part of a so-called swarm), the SARA system can provide
multiple insights enabling advanced collaborative behaviors.

When hosted on a UAS or drone; SARA’s subsystem can survey the battlespace, cue
the reconnaissance UAS or drone to high-interest regions of the battlefield and
support the host in characterizing the many installations in the region(s).

When hosted on a manned aircraft or a ground-based installation; SARA’s subsystem
can alert, locate and report the pace of local RF operations and support the host in
characterizing the local RF battlespace.

Low Cost, Lightweight

As few as 1 installation can alert the host of operations from the host’s entire
front or flank (+/- 45 degrees)

Multiple operationally-significant frequencies have been flight demonstrated;
technology has been demonstrated to be rapidly (<1 year) reconfigured to other
frequencies that are interesting for other missions.

TRL 7 – demonstrated in multiple, captive and free-flight tests on front-line US
weapons launched from front-line US aircraft.
